How to Set the Governor on a Tecumseh HMSK Snowblower Engine

Step by Step!
Today we're working on a Yardworks 10.5hp 29" snow blower with a Tecumseh HMSK105 engine.
My customer started to disassemble this when attempting to clean the carburetor himself, and ended up bringing it to us to fix.
The governor and carburetor linkage was also set improperly.
So in today's video, I'll be showing you how to properly set the governor, and also how to properly adjust the low idle RPM and also the high RPM setting.

This video is the gold standard of small engine repair videos !

[@richardsimon2072]

Perfectly said

[@dtsouza2519]

Finally...a very detailed, clear and concise video explaining how the throttle linkage and governor linkage works, and how to set it up. Thank you!

[@backdraftdragon3150]

I handle most of my repairs myself, your explanation and camera work is second to none. I wish I had come upon this video years ago. Great job, Thanks

Finally some who knows what they are doing and perfectly detailed information. Nice job

[@Dave-dh2fw]

This has got to be one of the most patient and detailed instructional video I've ever seen. Great work!

[@EliminatorPerformance]

Thanks Dave!

[@lawrencecarroll2031]

Love the EXTREME detailed explanations and close up video of your presentations! Keep 'em coming!

[@EliminatorPerformance]

Thanks for watching!

[@paulg444]

Thanks so much .. one thing I do with all these configurations, I reroute the fuel line around the tin housing. Takes more line but gets the line away from the hot engine case

[@JesseCase]

This was the exact kind of video I was hoping to find to help me with the 8hp Tecumseh on my Craftsman sleeve hitch tiller that I pull behind my garden tractor. You answered pretty much every question I had all with this one very clear and detailed video. Thanks for taking the time to post it! 😁

[@EliminatorPerformance]

Thanks for watching!

[@SimonQuigley]

Thanks mate. I picked up one of these off the side of the road that someone had given up on. They had a zip tie on the governor arm and it needed the carb cleaned. It's served me for a couple of seasons now, but it's been fiddly because the linkages are all mucked up. Now I should be able to fix it.

[@johnf6545]

This video saved my bacon, thanks! Rebuilt the carb on my brothers older snow blower including the manifold gasket. All looked good but must have been a slight air leak at the manifold, tightened it up a touch more and good to go, no more uncontrolled top speed.

[@TheCableguy4438]

Did this to my snowblower yesterday and now it runs like a champ 👍🏻

[@moosedog7360]

Great video. I was able to get my machine going perfect because of your way of articulating and the detailed close-ups throughout the entire video. I learned A LOT! Thank YOU!

[@AlFulmer]

Excellent video. Very clear instructions on setting the throttle/govenor. Especially helpful was the part about the lever falling down. That was my problem, and now that I fixed it, it works perfectly. Also helpful was the part on how to check the govenor to see if the gear was broken. Thanks!

[@peleger1]

Nice video. I put a brand new carb on my 25+ year old craftsman. I had my linkage on correctly but after this video, a few turns on both high and low idle screws it sure started running really smooth. Thanks!

[@RetiredGoodtimes]

Thanks. Such a simple thing made my throttle not work at all. Your instruction got me back on track and now it works. Yes, I replaced the carb and the throttle control. That is why it was not working. After that small little adjustment voila.

[@sam3344s]

Thanks, just put a new connecting rod in my 10hp Tecumseh and couldn’t remember how the throttle was set up. I just started it up and it runs pretty good.

[@redpine8665]

I have 3 of the HM80 Tecumseh engines with that set up. All 3 surge and hunt when not under load. When I'm using the machine on full throttle under load, they do not surge. I'm hopeful that the getting the governor set properly is the answer. Great video.

[@drewbarnes3160]

Once that throttle spring goes, good luck! No top end so it bogs down under load and throws snow half as far. Love figuring that out, thanks to this video, when there is a foot of snow in the driveway lol. It's like having a truck that the gas pedal stops half way. It'll get you to where you need to go but it will take twice as long. Great video, thanks man.

[@ricardomarmol1257]

Thanks Jake for an amazing detailed video and, complete explanation of how a Tecumseh snow blower engine works. Your video helped me to adjust the governor's linkage ,as well as the low and high speed rpms screws. I wish we had small engine mechanics in my area. Who really knows how to explain in detail how thin it works. Great video. I really appreciate it. You saved time and money. Thanks and God bless you and your beautiful family in this holiday season.Great video

[@patriclark2480]

Adjustment instructions at 5:00. Thanks for a great explanation!

[@chrisssmallengines7163]

Great video , when people make adjustments they should be using a tachometer to a specific RPM spec . The more important adjustment would be the HIGH or fast speed which should not go over spec RPM as to over stress engine components , this could result in engine failure . I know this is in other videos but I think that it should be mentioned at any time you talk about carb. adjustments .Thanks for the video .

[@EliminatorPerformance]

Yes definitely, I want to do a video on my STENS tachometer so it might make for a good follow up if I have the time!

[@simonmorneau7933]

You know perfectly how to explain things!!! Thank you so much!!👍🏻👍🏻☕️☕️☕️

[@EliminatorPerformance]

Thanks for watching!

[@Rein_Ciarfella]

Good one, Jake! 👍 I’ve already done a reset of high and idle speeds on one Tecumseh snowblower using my tach but didn’t understand the linkages to the governor so this really solidified my understanding in that area. Thanks!

[@EliminatorPerformance]

Thanks for watching!

[@kensmith6708]

Thanks again for sharing your knowledge and how to do it right videos. I like others I'm sure do appreciate how detailed your videos are and how you show the job being done step by step. I watch your videos and 2 other guys and I've learned alot from the 3 of you guys. Thanks again I truly appreciate what you do for us.

[@EliminatorPerformance]

Cheers Ken!

[@jesperkarlsson7230]

Ive been trying to get a used 90s 8hp Toro snowblower runnings and i must say your videos has been a great help! Now i have a new carb installed and it runs but only on full or half choke, so i guess im gonna look for air leaks! Cheers from Sweden!

[@escottn]

Thanks man for all of your videos. I enjoy watching them very much and learn so much. They are put together well and you explain everything incredibly clear. Thank you for sharing your years of acquired knowledge publicly.

[@EliminatorPerformance]

Thanks for watching!

[@fbbc6495]

Cool I fucked up the linkage and 10,000 red line put it the same as yours .and adjusted the governor. Now back out to do the snow. Great video . Thanks 😊

[@BobsYoureuncle]

Finally a tech that says the word Tecumseh correctly !

[@ussweeneyd]

Definitely the best tutorial I’ve watched so far. I have the same corrosion on my exhaust port so will try JB weld to regain a flat surface.

[@EliminatorPerformance]

Thanks for watching, glad it helped

[@jps99]

Great video! Excellent camera work and detailed narration. Also appredciate the absence of music. Earned my subscription!

[@rodneycallahan3117]

Thanks a lot for your detail instruction video, this engine and carb setup is identical to mine on a Noma Grand Prix 8.25, dual stage snow blower. I don’t know what year mine is, but it’s working well now, I’m going to order the electric start kit for it so my wife can use it. Thanks again.

[@bobpurs]

Awesome video bought used and it was reving way to high. Linkage and governor was wrong. Adjusted everything just like you showed. Running great now. Thanks

[@borimex5844]

[@jimmaloney6406]

Very thoughtful and informative. Thanks very much for sharing your knowledge and expertise.

[@tw1081]

Great video, good instructions. I followed them exactly but still have an unsteady rpm with the governor pushing the butterfly down then it revs up then it pushes down, then up, and so forth. All my neighbors hate me. What causes that condition? At full speed it runs sort of steady but it won't idle. Weak spring on throttle lever mechanism? I took off the float bowl, float, float needle, idle air needle, and then blasted carb cleaner in all the passages. New air filter. It is an 8hp Tecumseh wood chipper with original carb.

[@tonybayuk3712]

Thanks for this video. A Great resource adjusting my snow blower.

[@thomasstiglich3484]

Yet another amazing video from you. Thank you.

[@waynestefinashen239]

Excellent video and on some of your exhaust area video shoots you can tell that damaged muffler has been on for a while since it is damaged the aluminum exhaust port. Hopefully not too much! Good idea not running that blower without the muffler!

Still looking forward to your cameo appearance Mr Wayne. 🙂

Great video.

[@waynestefinashen239]

Thanks James . A generator question we had a Loncin LC3800DDC generator which showed a 110V output which i thought was abnormal because most show 120V. The original output was 57 hertz with 111.7 volts which we adjusted to 60 hertz 112volts. This should be fine but is it normal have not seen this before.

[@jcondon1]

@@waynestefinashen239 that generator seems to be sold in the UK with 110v and 230v output. No reason you could not run it at 60 hertz and bump the potentiometer up a little on the AVR to bring it closer to 120/240v. But 110/230 will not hurt anything as long as the hertz are at 60.

[@normtew6354]

Need to rebuild my carb on the 8 hp model of this engine. I will use your video to set it up. Who should I buy the carb kit or complete carb from? I do not trust some of the cheap ones I see for sale. Very well done video and explanation !!

[@echabot2721]

Nice video, well explained. Goes good when it's the same exact model blower as mine lol

[@echabot2721]

I did all the adjustments as described and for some reason when I throttle up, the engine surges. If I run it medium throttle there's no surge and seems to run fine when blowing snow. Just slightly weaker. Any higher rpm and it surges

[@EliminatorPerformance]

@@echabot2721 probably just need to make a main jet adjustment now that the rpm and governor are set properly kzbin.info/www/bejne/amGUiqqIoal8d7M

Love your vids man! Have you ever done a video on a Tecumseh 8HP m/n 155 026?? Mine has no primer bulb, and no lever controlled throttle. No choke lever either. It’s running good. I finally did my own valve job (thanks for all the excellent vids!). Bought that digital rpm tach you used in your previous video. I set my rig to around 3550. It’s rated for 4000, but I think my approach is sound. Again, thank you…

[@devonfullerton8160]

This is a fantastic video and you explained everything perfectly. I do have a question I hope I can get answered. My throttle linkage has the spring all hood uo and wrapped around but has no tension at all. It will not move the throttle linkage when I move the lever. Anyone got any ideas?

[@GregProulx-m5v]

Outstanding explanations on Tecumseh carb style and adjustments. Any video's on starter problems with 10.530 Tecumseh 1996' motors on a Husqvarna 10530 snowblower? Starter won't engage to ring gear but starter does run. Throwout gear appears to go to end of starter shaft and is clean-good spring too?

[@shandonbradfordoutdoors]

Great video! Thank you. Do you have a video of you attaching a throttle cable to this type of mechanism? I just bought a flat bottom boat with a Tecumseh HM80 mud motor set up, but the throttle wasn't connected in any way.

[@ONESNZER0S]

awesome video bro!!! good work.

[@EliminatorPerformance]

Thanks for watching!

[@egreenspot]

This video was so extremely helpful thank you so much. One question though, can I add an additional spring to increase tension on the throttle ?

[@saitekina_og9271]

Wish you would have shown the throttle more…the spring you are referring to on my machine it doesn’t move back (down) like yours did wondering if I need to do another wrap around??

[@gman100]

Great detailed video! I bought a similar machine, not running for five years, i put a new carb on it. It now runs, but seems to idle kind of rough and when i give it throttle it stumbles as it revs and lacks stability. It runs but not like it should. Any suggestions would be appreciated, thanks a lot. It's a Yard Machine 8hp 26" mdl. 31AS6FEF729

[@shawnfoster7546]

Hello.... I have the 45 inch 13hp craftsman and the throttle won't stay up in high idle it falls down... How do you fix that and this video is awesome.

[@brents.7535]

Wonderful video. Shop manual describes the governor adjustment poorly.

[@mikespain8655]

If all else fails, read the service manual, but people don't generally do that, they give up and let it sit, or bring it to a shop.

[@EliminatorPerformance]

Or get on Google, there's so much free information these days accessible by a cell phone

[@armourpc]

Great info. My 12hp Tecumseh CTC snow blower runs great but lately it will sputter and back fire intermittently when warmed up on high throttle it’s never been adjusted since new. It’s about 15 years old but works like new for then snow blowing operation. Any suggestions would be helpful I run non ethanol high test with sea foam. Thanks James
